Abstract (en)
[origin: WO2011012448A1] The present invention relates to a method for reducing metal oxides (3) to metallised material through contact with hot reducing gas, which is produced at least partly by catalytic reforming of a mixture of a gas that contains carbon dioxide (CO2) and/or water vapour (H2O), with gaseous hydrocarbons. The combustion gas for the burners (8a, 8b, 8c) supplying heat for the endothermic reforming processes occurring during the reforming is obtained at least partly from a partial quantity of the top gas arising during the reduction of metal oxides (3) to metallised material. Before being used as a component of the combustion gas, the partial quantity of top gas is first subjected to a dust-removal process and then to a CO conversion reaction, and the conversion gas obtained during the CO conversion reaction is subjected, after cooling, to a CO2 removal process. The present invention further relates to a device for carrying out the method.
